So i have an Fi Car Audio SSD 12 inch Subwoofer and a planet audio amp and the box is a groundshaker sqpxl 1 12 at 33 -35hz

and how do you guys think i should tune my amp to this setup 

 

 

what exactly do you mean by "tune" your amp?  Are you asking how to set your gains?  Where to set your subsonic filter?  Or whether or not to use bass boost, and if so then how much?  Need to eliminate the ambiguity from your question so as that we can give you the best informative answer.

 

Now, all that being said, here are some suggestions.

 

1:  Set your gains by ear, ensuring to listen for stress on the driver, and watching for clipping to ensure you are not overdriving your subwoofer.

2: Subsonic filter should be set at or just below tuning frequency of your enclosure to ensure you don't unload below tuning frequency driving the subwoofer past it's mechanical limits (very quick way to cause damage to a speaker, you will audibly hear it drive it's coil into the back plate or see it push out past it's physical limit and potentially rip/tear it's spider/surround)

3: Bass boost.  Leave this off.  That is all.

why leave the bass boost off

If you mean the remote knob, then you want to have that plugged in and turned all the way up while setting your gain. That's not meant to "boost" anything, just the ability to adjust the bass up to a certain point.

You should never use the bass boost on the amp or on the HU. When you dial the bass boost up you are essentially asking the amp to try to amplify the bass frequencies even more than it already is. There is almost no situation where that's a good thing. The reason why is because it will send the signal into distortion VERY quickly/easily and a clipped signal is a quick way to cause equipment failures. The amp will draw excess current resulting in undue strain on your electrical system and excess heat from the amp. The clipped/distorted output signal going to the sub(s) will heat the voice coils unnecessarily and if it/they are already being driven to the limits of it/their cooling abilities then damage will very likely result.

Just trust us, don't use the bass boost. Let your friends destroy their crap with it while you enjoy yours for as long as you own it.
